Dimensioning of RC filters for the elimination re-ignition phenomenon of the arc in the vacuum circuit-breaker - Summary

The frequency spectra and amplitudes of switching transients depend on several aspects, like layout of supply system, cable lengths, bus-bar lengths, operation of arc furnace, etc.

While the arresters selection is made on the basis of consolidated procedure, the design of RC dampers is carried out by the help of digital models. Thanks to the simulations, the optimal design of RC filters was made, eliminating the possible restrikes!
